Aim of This Review: Antitussives, more familiarly known as cough suppressants, are usually taken to suppress dry, irritating and patient-disturbing coughs. This review is an attempt to bring together some of the common medicinal plants traditionally used to manage respiratory disorders other than asthma. The review includes some information on traditional use of the plants as it relates to respiratory disorders, some chemistry and pharmacology in an attempt to ascertain their chemical composition and biological values, and so justify their uses. Study Approach: Information on the above was sourced from published articles and reviews on the subject available from various data bases and journals. Thirty-three medicinal plants drawn from twenty-two plant families were reviewed along with two natural products honey which always serve as vehicle for many plant medicines and bile. Findings: Table 1 gives a list of thirty-three plants used locally as antitussives. The various plant parts utilized in remedies include all the parts of the plant. The biochemistry and medicinal significance of tannins, terpenoids and essential oil components are now better appreciated in the management of respiratory disorders. Conclusion: Herbal antitussives not only suppress coughs, they always attempt to remove the respiratory disorders causing the coughs and thus make patients healthier. The use of medicinal plants remains a universal phenomenon; this review justifies the need for polyherbal formulations for use in the management of respiratory disorders. |
